Otis is 5 months old and has been ringing a bell to go outside for the last month !! I went on
www.poochiebells.com and bought a bell. The trainer at Petsmart told me to put a bit of butter on the bell and when he licked it( and the bell rang) to say "potty outside?" and open the door. It took him about 3 days w/ the butter to make a good connection with what he needed to do. Now he rings that bell all the time

!!
